📖 Introduction to Weight Measurements

🌟 Welcome to the World of Weight!

Weight is all around us! From the food we eat to the books we carry, everything has weight. In this interactive lesson, you'll discover how to measure weight accurately and use it in everyday life.

🤔 What is Weight?

Weight is how heavy something is. It tells us how much force gravity pulls on an object. The heavier something is, the more it weighs!

  • 🪶 A feather is very light
  • 📚 A book is medium weight
  • 🚗 A car is very heavy

🎯 Why Learn About Weight?

Understanding weight helps us in many ways:

  • 🍳 Cooking the perfect recipe
  • 💊 Taking the right medicine
  • ✈️ Packing for travel
  • 🏋️ Staying healthy and fit

🎯 Choosing the Right Unit:

💊 Use mg for:
• Medicine tablets
• Vitamins
• Spices in recipes
• Jewelry (gold, silver)
🪙 Use g for:
• Coins and small items
• Food ingredients
• Letters and postcards
• Mobile phones
🎒 Use kg for:
• People and animals
• Bags and luggage
• Books and furniture
• Sports equipment
🚗 Use tonnes for:
• Cars and trucks
• Large animals
• Building materials
• Ships and planes

🔄 Conversion of Units

1 g = 1000 mg
1 kg = 1000 g
1 tonne = 1000 kg

🔄 Conversion Examples:

📏 Small to Large Units (Divide)
  • 2500 mg = 2.5 g (2500 ÷ 1000)
  • 1500 g = 1.5 kg (1500 ÷ 1000)
  • 3000 kg = 3 tonnes (3000 ÷ 1000)
  • 750 g = 0.75 kg
📐 Large to Small Units (Multiply)
  • 2.5 kg = 2500 g (2.5 × 1000)
  • 0.5 tonnes = 500 kg (0.5 × 1000)
  • 3.2 g = 3200 mg (3.2 × 1000)
  • 1.8 kg = 1800 g
🧮 Step-by-Step Examples:
Example 1: Convert 2.75 kg to g
Step 1: 1 kg = 1000 g
Step 2: 2.75 × 1000 = 2750 g
Answer: 2750 g
Example 2: Convert 5500 mg to g
Step 1: 1000 mg = 1 g
Step 2: 5500 ÷ 1000 = 5.5 g
Answer: 5.5 g
Example 3: Convert 1.2 tonnes to mg
Step 1: 1.2 tonnes = 1200 kg (multiply by 1000)
Step 2: 1200 kg = 1,200,000 g (multiply by 1000)
Step 3: 1,200,000 g = 1,200,000,000 mg (multiply by 1000)
Answer: 1,200,000,000 mg

📝 Important Notes & Summary

📚 Key Points to Remember

Here are the most important concepts from today's lesson that you should remember!

⚖️ Standard Units

  • mg (milligram): Very small items (medicine, spices)
  • g (gram): Light items (coins, fruits)
  • kg (kilogram): Medium items (people, bags)
  • tonne: Heavy items (cars, elephants)

🔄 Conversion Rules

  • 1 g = 1000 mg
  • 1 kg = 1000 g
  • 1 tonne = 1000 kg
  • Multiply by 1000 to go to smaller units
  • Divide by 1000 to go to larger units

🎯 Choosing the Right Unit

💊 Use mg for:

Medicine, vitamins, spices, jewelry

🪙 Use g for:

Coins, food ingredients, small objects

🎒 Use kg for:

People, animals, bags, furniture

🚗 Use tonnes for:

Cars, trucks, large animals, buildings

🛠️ Measuring Tools

⚖️ Digital Scale:

Shows exact weight on a digital display. Great for cooking and precise measurements.

⚖️ Balance Scale:

Compares weights using two pans. The heavier side goes down.
